Claims priority, application Germany September 26, 1953 3 Claims. (Cl. 5758.65)

This invention relates to spinning machines, and more particularly to cabling spindles forming part of such machines.

It is an object of the invention to provide an improved whorl and thread storage member for cabled yarn spindles.

Other objects and the manner in which they are at tained, will become apparent as this specification proceeds.

In cabling spindles used up to now, the yarn issuing from the axle of the spindle passes through a radial slot in a thread storage disk, to collect in a storage groove provided on such disk. This arrangement involves the serious drawback that the thread issuing from the axle of the spindle or the hub of the whorl must be manually inserted in the slot-like channel in the thread storage member. If this insertion is not carried out properly by the operator of the machine, the yarn storage member is unable to perform its function, and the yarn is Wound up on the axle of the spindle, or on the hub of the whorl.

The invention contemplates avoiding this drawback by providing a combined whorl and thread storage member having a whorl portion, a frusto-conical portion, a groove and a thread overflow member. Preferably, the angle enclosed by the mantle of the frusto-conical portion should be smaller than 120, and the radial thread ducts of the thread storage member extend in the form of slots, across the entire frusto-conical portion.

This arrangement permits the thread emerging from the axle of the spindle, when it is drawn oif, to glide auto matically across the frusto-conical portion and into the groove of the thread storage member. All that is left to be done by the operator, is to draw the thread, once it has emerged from the axle of the spindle, through the thread-guiding eyelet which limits the outer balloon in axial direction, and to pass it on to the draw-off device.

In a further elaboration of the invention, the channel affording passage to the thread and extending in the frusto-conical portion, is enlarged in the direction toward the groove of the thread storage member whereby the automatic transfer of the thread into the groove is facilitated.

In the drawing attached with this specification and forming part thereof, an embodiment of the invention is illustrated diagrammatically by way of example.

In the drawing,

Fig. 1 is a front view of the new device, and

Fig. 2 is a side view thereof, in partial axial section.

Referring to the drawing, the axle 1 of the spindle mounts the combined whorl and thread storage member indicated as a whole, at 2 which comprises a whorl por tion 5, a frusto-conical portion 4, a groove 3 and a thread overflow member 11. The frusto-conical portion 4 tapers from the storage groove 3 so its part of smaller diameter merges into the axle 1 of the spindle or, as illustrated in the drawing, into the whorl portion 5. The

'ice

radial thread ducts 6 which extend from the thread passages 10 in the axle 1 of the spindle are provided in the form of slots extending across the entire side of the frusto-conical portion 4 and permitting the thread 8 deriving from the spool 7, to be drawn through the hollow shaft 9 of the spindle, the passage 10 in the axle 1 of the spindle, and one of the thread guiding channels 6 in the frusto-conical portion 4, by means of a suitably shaped threading wire. The thread then is pulled through the thread guiding eyelet (not shown in the drawing) which limits the outer balloon in axial direction, and passed to the draw-oil device (also not shown in the drawing).

When the thread is drawn, manually or by the draw-ofi device, through the thread guiding eyelet limiting the outer balloon of the yarn, the thread 8 emerging from the axle 1 of the spindle or from the frusto-conical portion 4 glides automatically along the mantle of the frustoconical portion 4 toward the storage groove 3 to enter the same when the cabling spindle is operated for thread storing purposes, and to pass from said groove across the thread overflow member 11 which revolves with and forms part of the thread storage member proper, to' the outer balloon of the yarn.

The mantle of the frusto-conical portion 4 may, if desired, be arched inwardly or outwardly to a certain extent; also, the mantle may comprise cut-out portions disposed between the thread guiding ducts 6, such modifications being clearly embraced within the framework of. the invention.

As clearly shown in the drawing, in order to safeguard still better the passage of the yarn on the thread storage member and into the storage groove thereof, the thread guiding ducts 6 provided in the frusto-conical portion i expand in the direction toward the storage groove 3.

I wish it to be understood that I do not desire to be limited to the details of construction, design and operation shown and described as modifications within the scope of the following claims and involving no departure from the spirit of the invention nor any sacrifice of the advantages thereof, may occur to persons skilled in the art.

' I claim:

1. A combined whorl and thread storage member for cabling spindles, comprising in combination, a whorl portion, a frusto-conical portion emerging from and expanding in a direction away from said whorl portion, a thread storage groove in the base of said frusto-conical portion, a thread overflow member disposed above said groove, and radial thread ducts extending from the center of the base of said frusto-conical portion, toward the side of said frusto-conical portion as well as toward its top, said ducts thus expanding as they approach the lateral confines of the frusto-conical portion, into openings extending over the entire side of the frusto-conical portion.

2. A combined whorl and thread storage member for cabling spindles, comprising in combination, a whorl portion, a frusto-conical portion emerging from and expanding in a direction away from said whorl portion, a thread storage groove in the base of said frusto-conical portion, a thread overflow member disposed above said groove, and radial thread ducts extending from the center of the base of said frusto-conical portion, toward the side of said frusto-conical portion as well as toward its top, said ducts thus expanding as they approach the lateral confines of the frusto-conical portion, into openings extending over the entire side of the frusto-conical portion, said frusto-conical portion tapering at an angle of less than 3.
